Application filed May3, 1918. Serial No. 232,364;

T 0 all whom it may concern:

Be it known that I, CLA ENCE R. EATON, a citizen of the United States,residing at Goldwater, in the county of Comanche and State of Kansas,have invented certain new and useful Improvements in Engines, of whichthe following is a specification.

This invention relates to internal combustion engines, and moreparticularly to an engine provided with a mechanism for supplyinglubricant to the bearing surfaces.

One of the main objects of the invention is to provide an internalcombustion engine of comparatively simple construction provided withsimple and efficient means for supplying lubricant to the bearingsurfaces. A further object is to provide a lubricating unit so mountedas to permit removal of the lower section of the crank casing with outnecessitating demounting or disassembling of the lubricating means.A-further' object is to provide-trough-like members in combination withdripping elements or ladles carried by the connecting rods of thepistons operative in the trough members for dipping oil therefrom whenthe connecting rods are reciprocated, means being provided for supplyinglubricant to the troughs. Another object is to provide a pump of simpleconstruction and operation which is so associated with the lubricatingunit as to be readily detachable, when necessary. Further objects willappear from the detailed description.

This baseis provided with suitably spaced openings in which are secured the lowerends of" the cylinders 2. Each of these cylinders is provided with anouter water jacket 3 and a cylinder head 41 secured thereon by means ofbolts 5, this head being provided with inlet and exhaust openingscontrolled by the valves 6 and 7, respectively. These valves are held inraised position, normally,

the valve stems and confined between the engine head and disks 9 securedon the valve stems adjacent the upper ends thereof.

A radiator 10 of any suitable. constructionis connected by means of apipe 11 to the water space of the front cylinder adjacent the lower endof'the water jacket 3, r I

the upper end or top of the radiator being connected by a pipe 21, tothe cylinder at the upper end of the water space. The water spaces ofthe two cylinders are connected by means of the tubularmembers 13 eachprovided with a union 14 so as to permit the cylinders to beindependently detached from base 1. Each cylinder is further provided,adjacent its lower end, with an outer annular flange 15 which is pro- 7vided with a plurality of spaced apertures to receive securing screws 16which are threaded into the base lthus detachably securing the cylindersto the base. By re,- moving these securing screws, the cylinders may beindependently removed from the engine base so as to permit ready accessto the interior of the cylinders and to the inv terior of the enginebase and crank casing carried thereby. I11 this manner, either one bereadily reposes.

A. piston 17 is operative in eachcylinder andisconnected by a connectingrod 18, to

acrank shaft19 rotatably supported in, the' base 1. The lower plate 20of thebearing sleeve of the connecting-rod. 18 is provided with adownwardly directed substantially triangular dipper21 the apex of whichis directed downwardly. This dipper is in yer ticalalinement withanyarcuatextrough 22 V which is of substantiallysemi-circular shape,

When the engine is in operation, the dippers 21 will be lowered into thetrough 22 and moved through the same, these clippers being then raisedout of the trough and moved in a reverse direction so as to dischargethe oil or.other lubricant contained thereby.

Each of the troughs 22 is provided, at its lowermost point, with anopening which receives a nipple 23 carried by a T 24 which is interposedin an oil pipe 25. This oil pipe communicates at its lower end with themain bearing indicated generally by 26 of the main crankshaft 19. At itsinner end, the pipe 25 communicates with a T connection 27 which isthreaded onto the lower end of the cylindrical discharge spout 28 of anoil pump 29. Oil is supplied by this pump to the trough 22 and to themain bearings 26, when the pump is operated, so as to iii-- sure properlubrication of the bearing. The body of pump 29 is divided by a centralweb 30 into an intake chamber 31 and an exhaust chamber 32. The lowerend of the intake chamber 31 tapers downwardly to provide a seat for aball valve 33 mounted therein which controls the intake opening 34.Upward movement of this valve is positively limited by arod 35 whichextends across the lower portion of the intake chamber above the valve.A suitable screen 36 is screwed onto the lower end of the intake chamberand, when the pump is in operative position, this screen projectsinto-an oil well formed inthe crank casing 38. An upwardly projectingwall 39 is formed inthe intake chamber 32,'this wall serving with web 30to provide a valve chamrod 41 similar to rod 35.

her which receives the ball valve 40 for controlling "communicationbetween the intake and exhaust chambers, upward movement of this valvebeing positively limited by a A piston 42 is operative in the barrel 43of the pump, this piston being connected by a piston rod 44' to aneccentric disk 45 keyed on a cam shaft 46 rotatably supported in thebase 1. The

eccentric'disk 45 is provided with a central peripheral groove whichforms lateral retaining flanges between whichis mounted a connectingstrap or collar 47 which serves to loosely connect the upper end of thepiston rod- 44 to the disk in the well known manner. .A spur gear 48 iskeyed on cam shaft 46 and'meshes with a similar gear 49 keyed on thecrank shaft '19. In this manner, when the crank shaft is rotated, the

cam shaft will be rotated so as to reciprocate'the piston of thepumpthus drawing oil into the intake chamber 31' and forcing this oilinto and through the exhaust chamber 32-to the main bearingof the crankshaft and to the trough 22. To permit removal of the gear 49, one crank50 of the crank shaft 19 is detachably secured to the body.disposedlaterally of the utilized for d iving a b lt pulle when" it is'portion of the shaft, as will be clear from Fig. l of the drawings Thepump 29 is supported by a bracket 51 which is shaped to fit about oneside and the top of the pump, the upper end of this bracket beingbifurcated to fit aboutt-he lateral faces of a bearing beam 52 extendingtransversely of the base 1, this beam being provided with lateralrecesses to receive the arms at the upper end of'the bracket. 7 Thisbracket is detachably secured to the beam by securing bolts insertedthrough the arms of the bracket and threaded into the beam, and the pumpis similarly secured to the bracket so as to be detachable therefrom.The pump and the parts associated therewith constituting the lubricatingunit are thus all supported by the base 1 so that the lower sec tion ofthe crank casing 88 may be removed without disturbing the lubricatingunit thus permitting ready access to the same. The central bearing forthe main crank shaft will be thoroughly lubricated by the oil which issplashed thereon during the operation of the engine due to the action ofthe dippers 21 in thetroughs 22.

Cam shaft 46 is provided with a plurality of cams 53 secured thereonwhich engage the lower ends of operating rods or plungers 54 which arereciprocably mounted in the upper section of the crank casing, a rod 55being adj ustably secured to member 54 at its lower end, this rod beingoperated through a bracket 56 projecting from the engine head 4. Theupper end of rod 55 is of rounded or substantially spherical shape andis operative in a corresponding recess in the outer end of a rocker arm57 which is rockably mounted for movement about a horizontal axis in asupporting frame 58 formed by an extension of one of the securing bolts5. The inner end of rocker arm 57 engages the upper end of the valvestem so as to depress the valve when the outer end of the arm is raised,the valves being depressed andraised in succession so as to admit'anexplosive mixture to the cylinders, and permit the productsof'combustion to be expelled'there- 60 is secured on the forwardcml-ofstub shaft 62 secured on the fan shaft 63 rotatably supported in the fanbracket 64 secured to the casing l adjacent the front thereof. A fan 65of suitable construction is secured on shaft 63. In this manner,rotation is .im-

parted to the fan direct from the crank shaft. A bevel gear 66 issecured on'stub. shaft 59 and meshes with a similar gear 67 shaftwhichmay be posed beneath said desired to use the engine for belt work,or for any similar purpose desired. Crank shaft 19 is provided, at itsother end with a substantially disk shaped head 66 to which is securedthe fly wheel 67. Fly wheel 67 is provided, in its outer face, with asubstantially frusto-conical recess indicated by 68 adapted to receive aclutch cone for operatively connecting the crank shaft to a transmissionshaft.

As will be noted more clearly from Fig. 2 of the drawings, the endportions of the cam shaft 16 are rotatably supported by bearing members69 and 70 mounted in the base section 1 of the casing. The bearingportion of shaft 46, at each end thereof, is provided with oppositelydirected helical grooves 71, which cross and extend inwardly fromcollars 72 secured to the shaft adjacent the inner end of the bearingmember. The inner ends of these grooves 71 terminate closely adjacentconcave oil receiving members or cups 73 which are secured to the shaft4L6 and project substantially radially therefrom. These members areadapted to receive oil which is projected thereon during the operationof the crank shaft, this oil being directed into the grooves 71 by meansof which it is conducted onto the bearing surfaces of the end portionsof the shaft. This insures proper lubrication of the bearing portions ofthe shaft so as to prevent looseness or excessive wear thereof.

To permit access to the gears 48 and 49, I provide a gear housing 7 3which is detachably secured to the upper section 1 of the casing,thishousing being in alinement with the gears. By removing housing 7 3,ready access to the gears is obtained as will be evident.

The foregoing description and the drawings have reference to what may beconsidered the preferred, or approved, form of my invention. It is to beunderstood that I may make such changes in construction and arrangementand combination of parts, ma terials, dimensions, etc., as may proveexpedient and fall within the scope of the appended claims.

llaving thus fully described my 111V611 tion, what I claim as new anddesire to secure by Letters Patent, is:
